b IMPROVEMENT IN MACHINES FOR EDGING SHINGLES.

i Specification formirg part of Letters Patent No. 148,799, dated Match 24, 1874; application filed J une 19, 1873.

T0 all whom it may concern: thereby diSconnecting the pulley or pinion 6 Be it knoWn that I, JAMES E. AUS1IN, of Oswego, in the connty of Oswego, in the State of New York, have invented a neW and useful Improvement in Machine for Edgng Shingles, of which the following taken in connection With the accompanying drawings, is a full, elear, and exact description.

In the drawings, Figure 1 is a side view of my newly invented shingle paralleledging machine. Fig. 2 is an end view of same. Fig. 3 is a top view; and Fig. 4 is a section through a a, showing more fnlly the arrangement for gaging the movable saw and the device for connecting and disconnectng the feed.

Similar letters of reference indicate corresponding parts.

Shingles generally are wider at the but-t than at the top, and When laid on the roof the former Will be close to each other, and leave the latter apart, thus forming receptacles for the water, Which is foreed to spread under the shingles, and is there retained. The action of the Sun on the top side With the water on the under side has a tendency t0 warp and rot the shingles.

My invention has for its object to furnish a shingle paralleI-edging machine Whioh shall trim and form the shingles so that nheir sides shall be parallel and at right angles to the bottom edge and Will lie close, uniform, and true, and hence Will save time in laying, and 1ast mach longer than ordinary shingles, the machine being constructed and arranged as hereinafter described.

A is the driving or main pulley. B is the frame. 0 is a drum on the shaft otthe driving pnlley, and drives the saws by means of the belt D and pnlley E. F is a pulley on the same shaft, and drives the drnm G. E K is a pulley on the same shaft With the drnm G. The former drives the longitudinal shaft H by the belt I and pnlley K. 10 is a pulley or pinion on the shaft H, and drives the drum or wheel L, and with it the roller a. 6 is another pulley or pinion on the shaft H. The latter rnns in the arm or bar (1, which is hinged on and suspended from the arm 12. The lower end of the bar (1 is pressed ontward by a spring,

from the drum or wheel f. The lower end of the bar 61 is also connected With the foot-lever b by the rods c c and elbow-crank, so that When the foot-lever is pressed clownward the bar cl is forced inward, connecting the pulley 6 With the drum f. S is a roller for guiding the shingles from the saws, and is in a hinged frame, M. u is a spring attached'to the frame M at one end, the other end resting on the bar t, for the pnrpose of holding the shingles while the edgings separate from them until forced ont over the end of the bar by sncceeding ones. N N are bars for steadying the shingles as they pass between the saws. 70 is a stationary table or platform, upon which the shingles are placed. i 73 are chain-wheels driven by drum or wheelf, and connected by ehains. 0 0 are guide-bars attached to the chains for the purpose of forcing and gniding the shingles 11nder the saws. X is a circnlar saw attached to the shaft. Y is a circular sa: attached to a loose sleeve, which slides on a feather in the shaft. q is a table resting on the movable sleeve P. To the table q is fastened the standard and collar R. 27 is an arm for moving the loose sleeve P. 0 is a horizontal bar, to whioh the arm 19 is attached. n is a lever for operating the horizontal bar 0. m is a gage with a handle attached, sliding on a bar across the end of the frame. This gage has a pin which passes through the lever n, thereby forming a connection with the loose saw Y. The wheels and L and their auxiliaries may be either pnlleys or cog-wheels.

In operating the machine, the shingles are placed on the table k so that their bottom or lower edges Will rest against the guide-bar 0, and one edge is Within the cutting line of the stationary saw X; then the movable saw Y is set for the opposite edge by means of the gage m and its connection with the lever 77,, horizontal bar 0, arm 19, and movable table q. The chainwheels i i are then set in motion by pressing the foot-lever b downward, which, by its connection With the bai d, forces it inward, and connects the pulley or pinion 6 with the drum or wheel f, the pulley f being on the shaft of the chain-wheels i 2'. As the chains,

with their guide-bars 0 O, traverse over the table 7:, they Will carry the shingles forward to the saws X and Y, from whence they are drawn and gnided by the rollers 9 and S, and forced ont between the bar t and sprng u,

where the edgings Wi1l separate from them.

l+rom thence they are forced over the end of the bar 2? by succeedng shingles. When the foot-lever 6 is pressed downward, the lever v Will catch and hold the same until the upper end of the latter cornes in contact with the guide-bars O 0, When t Will be thrown offthe foot-lever, thereby stopping the chain-wheels and their anxiliaries, and giving the operacor time for feeding the machine.

What I daim as new, and desire to sec1ue by Letters Patent, is

In a shingle paraflel-edging machine, in combnation with a stationary saw, the movab1e saw Y, with its standard'and collar R, and movable table q, construcd and arranged in such a manner that the saws Will ont under the arbor, substanally as shown.

In testimony wherecf I have signed my name and afixed my sea1 in the presence of two attesting wionesses, at Oswego, in the connty of Osweg0 and State of New York, this 13th day of J une, 1873.
